Excel formula to calculate hours worked and overtime [with template]

excel formula to calculate hours worked and overtime

It is easy to build an Excel formula to calculate hours worked and overtime of your employees. This is why Excel is widely used in the workplaces. It makes any calculation very easy.

The Excel template I have made for this article can be directly used in your workplace.

Most companies calculate work hours and over time based on the 40-hours-work-week (8 hours per day). By default, my Excel template also calculate work hours and overtime based on the 40-hours-work-week. But if your company takes different hours-work-week, you can define that in the template.

In this Excel template, over time is calculated based on the whole week, not based on an individual day. Suppose, an employee has worked 9 hours on the very first day of the week. But his total hours in the week does not exceed 40 hours, he will not be rewarded any over time.

You can also define different hourly rates for Regular Works and Over Time Works.

This is the template overview. This template is printable in one page (perfect for Letter and A4 Page with Landscape Orientation) without any modification.

The inputs in the Excel Template

Put the following inputs in the Excel template (image below):

Overtime Counted After: Generally, this is 40 hours per week. If your office maintains 45 or other working hours, input that value in this field. Working hours vary from country to country.

Hourly Rate:

Normally Working Hour Rate is different from the Over Time Hourly Rate.

  • Regular: Input the Regular Hourly Rate
  • Over Time: Input the Over Time Hourly Rate

The template takes 4 time-inputs (above image):

  • Time In: This is the time when the employee enters into the working place.
  • Lunch Starts: Time when the lunch starts in the working place.
  • Lunch Ends: Lunch end time entry.
  • Time Out: This is when the employee completely leaves the office place.

Outputs we get automatically

These are the outputs we get from our inputs:

1) Total Hours:

This “Total Hours” is calculated for an individual day. We have used this formula in the cell G16 to get the total hours: =((F16-C16)-(E16-D16))*24

excel formula to calculate total hours worked

  • (F16-C16) is actually (Time Out – Time In). And (E16-D16) is (Lunch Ends – Lunch Starts).
  • We multiplied ((Time Out – Time In) – (Lunch Ends – Lunch Starts)) by 24 to covert it into hour value.
  • This is why we get the value in Number Otherwise, subtraction of two times results in Time format.

Time converted to number format

2) Over Time Hours

Though the template shows the Regular Hours before the Over Time Hours, I actually calculated the Over Time Hours before the Regular Hours. This is the formula I have used in the cell I16 to calculate the Over Time Hours:


Where, work_hours_per_week = D12

How does this formula work?

  • This formula has an expanding range. It is $G$16:G16. For the next cell (I17) in the column, this range will be: $G$16:G17. You see the range has expanded. This is why it is called expanding range.
  • logical_test: IF function checks whether the sum of the expanding range has exceeded the value of work_hours_per_week.
  • value_if_true: If the sum exceeds the value, the IF function returns this value: SUM($G$16:G16)-work_hours_per_week.
  • value_if_false: Otherwise the IF function returns value 0.

Let me check this formula for the cell I21: =IF(SUM($G$16:G21)>work_hours_per_week,SUM($G$16:G21)-work_hours_per_week,0)

excel formula to calculate overtime

  • =IF(47.25>40,47.25-40,0); [I have replaced some parts of the formula with their values]
  • =IF(TRUE,7.25,0)
  • =7.25

So, the formula returns value 7.25.

3) Regular Hours

To calculate Regular Hours, I have used this formula in the cell H16: =MAX(G16-I16,0)

This formula returns the maximum one between these two values: G16-I16 and 0.

4) Total Hours (Regular)

Total regular hours calculated

5) Total Hours (Over Time)

Total over time hours calculated

Cell I22 actually holds our total Over Time hours. So, we just refer that cell in the cell I23.

6) Total Pay (Regular)

Total regular pay

Multiplication of the Regular Hourly Rate and total Regular Hours.

7) Total Pay (Over Time)

Total Over Time Pay

Multiplication of the Over Time Rate and total Over Time Hours.

8) Grand Total Pay

Total Grand Pay

Sum of Regular Pay and Over Time Pay.

    What if your company rounds the time? For example: When I clock in at 06:07 it calculates my time starting at 06:00 but if I were to clock in at 06:08, my start time is calculated at 06:15. By the way, Your emails are great. I highly enjoy them.
